flibs - a collection of Fortran modules SVN

Add test program for the string operations module

Add new functions to the set of string operations - extensions to trim()

Preliminary commit of a module for simple string operations

Add a check for the Fortran 2018 feature that elemental functions are allowed to be recursive.

Add two experiments - lambda expressions and the prototypes pattern

Add a check for the availability of reduction routines for coarrays.

Add a new check to the collection - checking that with coarrays files are opened independently

Update of a few checking programs

Add check for C_PTRDIFF_T - defined by Fortran 2008

Add makefile for the test programs in filedir.

Note: the modules in filedir and platform require modernisation to make use of standard facilities as much as possible. Fortran 2003 gives enough possibilities for this.
